plotter-data

[Function]
  `(``plotter-data` plotter {keyword value}*`)`

Returns the data sets loaded in plotter according to keyword arguments.

`plotter-data` supports the following keyword arguments:

`:layer` {`:front` | `:front-selection` | index}
  If `:layer` is not specified then data from all layers are returned. If only one layer exists, or if `:layer` is `:front` then only the front layers's data is returned. If `:layer` is `:front-selection` then only the currently selected points (if any) in the front layer are returned. Otherwise the value should be the zero-based index of the layer to return. Layers are stored in the order they were created.
`:xy` boolean
  Determines if CLOS objects or xy coordinate numbers are returned as data. If `:xy` is not specified then `point` data are converted to xy coordinate values but other CLOS instances are not. If the value is false then layer objects are returned. If the value is true then numerical coordinate values are returned and the value of `:x-decimals` and `:y-decimals` determines their value formatting.
`:x-decimals` {boolean | integer}
  Specifies the number of decimal places to which x values in `:xy` coordinate lists are rounded to (if :xy is true). If boolean true (the default) then x values are unchanged. If false then x values are floored to the nearest integer. Otherwise the value should the number of decimal places that data values are rounded to. Specifying zero causes data to remain floating point but without remainder.
`:y-decimals` {boolean | integer}
  Exactly like `:x-decimals` except that it applies to y values.
